Description

[Detailed explanation of the idea] This invention relates to a vacuum cleaner.

Conventionally, as shown in, for example, Japanese Utility Model Application Publication No. 51-40155, there has been a main body case with a built-in electric blower and a cord reel device, and a dust collector that is detachably and self-sealing connected to the communication opening of the main body case to the blower. A vacuum cleaner is known that includes a case and a cylindrical wave filter provided within the dust collection case.

This vacuum cleaner removes dust from the corrugated filter by flicking the exhaust surface of the corrugated filter with a striking part using the driving force of the cord reel device.

Furthermore, as disclosed in, for example, Japanese Unexamined Patent Publication No. 51-82966, a vacuum cleaner is known in which dust is removed from the corrugated filter by flicking the intake surface of the corrugated filter with a striking portion.

However, in all of the conventional vacuum cleaners mentioned above, one side of the cylindrical waveform filter is flicked by the striking part, and the waveform filter is driven from only one direction. There was a problem in that the trapped dust was difficult to remove.

This invention solves the above-mentioned problems, and by repelling the cylindrical wave filter from both the intake and exhaust sides and applying vibration from both directions, dust can be removed from the wave filter using the driving force of the cord reel device. The purpose is to provide a vacuum cleaner that is efficient and works well.

That is, in this invention, a one-way clutch is interposed between the drive shaft driven by the driving force of the cord reel device and the cylindrical waveform filter, and the waveform filter rotates when the one-way clutch is engaged. The exhaust surface of the corrugated filter is repelled by the main striking part, and an auxiliary striking part is connected to the drive shaft to make the striking force of the main striking part stronger than that of the auxiliary striking part, so that when the clutch is disengaged, The waveform filter is stopped at the main striking force section, and the auxiliary striking section rotates together with the drive shaft, so that the waveform filter is repelled by the auxiliary striking section.

Therefore, according to this invention, the waveform filter is repelled from both the intake and exhaust sides by using the driving force generated by pulling out and winding the cord of the cord reel device, and by applying vibration to the waveform filter from both directions, Trapped dust can be dropped in a direction where it can easily fall, making it possible to efficiently and easily remove dust from the corrugated filter.

An embodiment of this invention will be described below with reference to the drawings.

Reference numeral 23 denotes an auxiliary striking part which is connected to the other end of the drive shaft and which, when rotated, repels the protrusion 13A provided on the end face which is the intake surface of the waveform filter 13 to remove dust from the waveform filter 13; The striking force during its operation is made weaker than that of the striking part 17.

Reference numeral 24 denotes a one-way clutch A having one end supported by the end of the bearing hole B14 of the wave filter 13 and the other end consisting of a coil spring wound around one end of the drive shaft 18.
The rotation of the coil spring is transmitted to the waveform filter 13 only in one direction, that is, only in the winding direction of the coil spring, and when the rotation is in the other direction,
The coil spring has a large diameter and is caused to slip between the coil spring and the drive shaft 18, so that rotation is not transmitted to the wave filter 13.

25 is the other end of the drive shaft 18, and a coupling tool A126 rotatably supported between it and the auxiliary striking part 23 has one end supported by the coupling tool A25 and the other end wound around the drive shaft 18. The one-way clutch B made of a coiled spring transmits rotation only in the same direction as the one-way clutch A24.

27 is attached to the drive shaft 1B, and the waveform filter 1
This is a packing plate that seals the 814 portion of the bearing hole No. 3.

28 is a pre-filter detachably attached to the frame wall plate 9 so as to cover the periphery of the wave filter 13;
It has a net 29 on one side, a support hole 30 in the center, and a door 31 below to throw away the dust removed by the corrugated filter 13 to the outside.

Reference numeral 32 denotes a dust remover that comes into contact with the outer surface of the net 29 of the pre-filter 28. One end of the dust remover passes through a support hole 30, and a connector B33 is attached to the connector B33, which is detachably connected to the connector A25.

Reference numeral 34 denotes an intermediate connector rotatably supported by the frame wall plate 9, and one side thereof meshes with the gear of the rotator 22.

Reference numeral 35 denotes a transmitting device, which is detachably connected to the other side of the intermediate connecting device 34, and transmits rotational force by the cord reel device 3 when the dust collection case 5 is connected to the main body case 1. It is.

Since the vacuum cleaner of this embodiment has the above-described configuration, when the cord is pulled out from the main body case 1 during use, the rotational force of the cord reel device 3 is transferred to the rotating tool 22 via the transmitting tool 35 and the intermediate connector 34. communicated.

Naturally, the drive shaft 18 coupled to the rotating tool 22 also rotates.

As a result, the one-way clutches A24 and B26, which are made of coil springs wound around the drive shaft 18, each have their coil springs tightened, and the dust remover Rotate.

Naturally, the auxiliary striking part 23 coupled to the drive shaft 18 also rotates.

Therefore, fine dust attached to the waveform filter 13 is
The dust is removed by being repelled by the main striking part 17 and falls into the pre-filter 28.

Coarse dust adhering to the net surface 29 of the pre-filter 28 is removed by the rotational force of the dust remover 32.

However, since the corrugated filter 13 is also rotating, the auxiliary striking part 23 does not perform a dust removal function.

In this way, by pulling out the cord during use, each type of dust removal can be performed.

Thereafter, by cleaning, the pre-filter 28 captures coarse dust, and the corrugated filter 13 captures fine dust.

After that, when the cleaning is finished and the cord is wound up on the cord reel device 3, the rotational force is transferred to the rotating tool 22 in the opposite direction from when it is pulled out.
transmitted to.

The coil springs of the one-way clutches A, B, and 24.26 each attached to the drive shaft 18 have large diameters and slip, causing the wave filter 13 and dust remover 32 to slip.
Do not give rotation to.

At this time, since the auxiliary striking part 23 has a weaker striking force than the main striking part 17, the rotational force of the wave filter 13 is stopped by the main striking part 17, and only the auxiliary striking part 23 provided on the drive shaft 18 It rotates and gives vibration to the waveform filter 13, giving it a dust removal effect.

As explained above, the vacuum cleaner according to this invention includes a main body case that houses an electric blower and a cord reel device,
A dust collection case is removably connected to the communication port of the main body case to the blower, and a dust collection case is removably connected to the communication port of the main body case so as to close the opening provided opposite to the communication port of the dust collection case. A frame wall plate having pores, a cylindrical waveform filter rotatably supported by the frame wall plate, a drive shaft disposed at the center of the waveform filter and driven by the cord reel device, and rotation of the waveform filter. a main striking part provided on the frame wall plate so as to sometimes repel the exhaust surface thereof; an auxiliary striking part connected to the drive shaft to repel the intake surface of the corrugated filter; and an auxiliary striking part interposed between the drive shaft and the corrugated filter. The device is equipped with a one-way clutch that is engaged by the rotation of the drive shaft in the cord reeling direction of the cord reel device. The dust is transmitted to the corrugated filter, and the main striking section fixed to the exhaust surface of the corrugated filter hits it to remove dust.At this time, the second striking section rotates together with the corrugated filter, so that the dust is not removed, and the cord is not wound. When this occurs, the one-way clutch is disengaged, and the rotation is not transmitted to the waveform filter, which requires a large rotational force. By hitting the main striking part and blocking the rotation of the waveform filter, the auxiliary striking part, which rotates together with the drive shaft, is activated by the waveform filter. Therefore, the corrugated filter is exhausted by the main and auxiliary blowing parts by the same drive shaft, and dust is removed from the suction surface side, which is advantageous in terms of workability and cost, and has a good dust removal effect on the corrugated filter. improved,
Furthermore, when winding the cord, rotation is not transmitted from the drive shaft to the waveform filter, making it possible to reduce the load during winding.The auxiliary striking part has a lighter load than the main striking part, so the cord reel device Even if the winding force of the coil spring is not too large, the cord will not be wound up securely, and as a result, the winding force of the coil spring will be too large and a large force will be required to pull out the cord. Also, even if the cord is caught in the dust collection case when it is removed from the main body case, the cord will not be caught in at high speed and become dangerous.
